Problems solved by technology

Therefore, it is difficult to popularize
[0004] In the prior art, there is also a device that is directly equipped with exhaust gas treatment for the exhaust port. However, when the exhaust gas in the anesthesia machine is discharged, it will form attachments from the inside to the outside of the machine due to environmental changes, and impurities in it may accumulate, affecting exhaust

Embodiment 1

[0026] see Figure 1~3 , in an embodiment of the present invention, an anesthesia machine waste gas extraction and recovery device for anesthesia departments includes a suction mechanism for suction and a cleaning mechanism for treating exhaust gas, and the extraction mechanism and cleaning mechanism are both placed on the On the bottom plate 1 , the detachment mechanism communicates with the cleaning mechanism through the air pump 5 , and the detachment mechanism is slidably arranged on the support cylinder 2 .

[0027] Described detachment mechanism comprises the suction hood 4 that is used to fit on the waste gas outlet of anesthesia machine, and described suction hood 4 is a cover-like structure, and the edge of described suction hood 4 is bonded and is provided with rubber washer; The corrugated pipe and the strut 3 communicate with the intake end of the air pump 5; the strut 3 is a through-pipe structure, the upper end of the strut 3 communicates with the end of the exha...

Embodiment 2

[0033] see Figure 4, in order to avoid anesthesia machine waste gas and impurities therein from accumulating at the outlet of the waste gas pipeline, in an embodiment of the present invention, an anesthesia machine waste gas extraction and recovery device for anesthesia departments, on the basis of embodiment 1, the air extraction The open end of the cover 4 is inlaid with a bracket 41, the middle part of the bracket 41 is rotatably connected with a rotating shaft 42, and the periphery of the rotating shaft 42 is fixed with a plurality of groups of fan blades 43, and the fan blades 43 are fixed on the rotating shaft by welding. 42, the surface of the fan blade 43 is fixedly connected with densely covered bristles 44, so that when the air pump 5 pumps air through the exhaust cover 4, the airflow drives the fan blade 43 to rotate through the rotating shaft 42, so that the fan blade 43 drives the bristles 44 to rotate continuously To clean the position of the exhaust gas outlet,...

Abstract

The invention discloses a waste gas exhausting and recycling device for an anaesthesia machine for the anesthesia department. The waste gas exhausting and recycling device comprises an exhausting mechanism used for inhaling and a cleaning mechanism used for treating waste gas, wherein both the exhausting mechanism and the cleaning mechanism are mounted on a bottom plate; the exhausting mechanism communicates with the cleaning mechanism through a gas pump; under gas exhausting action of the gas pump, the exhausting mechanism rotates and cleans a contact surface; and the exhausting mechanism isarranged on a supporting barrel in a sliding mode. According to the waste gas exhausting and recycling device disclosed by the invention, in use, a gas exhausting cover is fitted to a waste gas outletof the anaesthesia machine, and then, the gas pump can be started for completely and intensively exhausting waste gas through a gas exhausting cover, and gas flow drives fan blades and bristles to continuously rotate to clean the position of a waste gas hole, so that a cleaning problem caused by impurity attaching can be avoided; harmful substances in the waste gas are removed after the waste gaspasses through an alkaline solution, alkaline steam in tail gas is cleaned by cleaning water and then is dried through active carbon particles for being discharged; and a gas exhaust pipeline can bedesigned to improve contact efficiency of the gas and the active carbon particles in the drying cavity to improve drying and drying treatment effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anesthesia machine waste gas extraction and recovery device for an anesthesia department. Background technique [0002] At present, the anesthesia machines commonly used in the anesthesia department of the hospital do not have an exhaust gas discharge system. The exhaust gas during anesthesia is usually discharged directly into the anesthesia operating room, which not only easily causes secondary inhalation of the patient, affects the inhalation dose of the anesthetic, but also easily Inhaled by medical staff in the operating room, affecting the normal work of medical staff, it is easy to cause dizziness, fatigue, lack of energy and other problems in a short period of time. Therefore, necessary devices are needed to discharge the anesthesia waste gas in time. [0003] At present, for the discharge of anesthesia waste gas, the central waste gas pumping method is mostly...
